Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Since this is an HTML Injection vulnerability, standard mitigation involves proper input validation and output encoding to ensure user-supplied data is safely handled before rendering in web pages. Monitor vendor advisories for any future patches or updates addressing this issue.

Description

CVE-2025-62320 is an HTML Injection vulnerability in a web application product that arises when user input is not properly validated or sanitized before being displayed on a webpage. This flaw allows attackers to inject arbitrary HTML code, which may cause the user's browser to interact with unintended external resources, leading to unexpected requests. The vulnerability has a medium severity score of 4.7 and does not involve direct compromise of confidentiality, integrity, or availability beyond limited impact.

Impact

An attacker can inject arbitrary HTML into the affected web application pages, causing users' browsers to load external resources without their intent. This may lead to privacy concerns or indirect information leakage but does not directly compromise data integrity or availability. The impact is limited to partial confidentiality loss as per the CVSS assessment.

Summary

This vulnerability involves improper input validation in a web application, allowing an attacker to inject HTML code into web pages viewed by other users. The injected HTML can cause the browser to automatically load external resources, potentially leading to unwanted network requests. The CVSS 3.1 vector indicates the attack can be performed remotely over the network with low complexity and no privileges required, but requires user interaction. The scope is changed (S:C), and the impact is limited to partial confidentiality loss (C:L) without integrity or availability impact.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
